Al-Fawz al-Kabir fi Usul at-Tafsir : The Great Victory on Qur'anic Hermeneutics; is a manual of the principles and subtleties of Qur’ānic tafsīr. In it the author outlines the five fundamental sciences that the Qur’ān contains: the science of judgements (ahkām),
reminding others of the Favours of Allah, the Days of Allah and the
Life after Death, and giving particular attention to the science of
polemics. He also reviews the other sciences of tafsīr such as the circumstances of revelation (asbāb an-nuzūl), abrogating and abrogated āyāt (an-nāsikh wa’l-mansūkh) and the unusual words and phrases of the Qur’ān (gharā’ib al-Qur’ān),
before concluding the book by looking at the extraordinary and
miraculous aspects of the Noble Book, and a final chapter on the
meanings of the letters of the Arabic alphabet.

This important work is ideal for those who are studying the Qur'an or simply need a better and clearer understanding.
